VENTILATED HATCH.

SPECIFICATION forming part of Letters Patent N 0. 650,477, dated May 29, 1900.

Application filed May 18, 1899. Serial No. 717,268. (No model.) i

To all whom it may concern:

Be it known that I, HARRY M. MoINrosH, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ventilated Hatches, of which the following is a specifi cation.

My invention relates,primarily,to that class of ventilators in which an opening or hatchway in the top or roof of a storage-apartmentsuch, for instance, as a car-body-is made use of as a passage-way for the ventilating-current. Its objects are to vary the ordinary standards of construction as little as possible, to do away with unnecessary parts, and to provide a simple but strong, durable, and effective hatch or cover for such openings which will at all times protect the contents of the storage-space and yet will afford means for directing the ventilating-current through the same.

For a proper understanding of the invention it will be sufiicient to describe it in connection with an ordinary ventilated or refrigerator car.

In the drawings, Figure 1 is a perspective view of a car-body, showing my. device attached thereto. Fig. 2 is an enlarged perspective of one of my ventilated hatches on a portion of a car-roof, the remainder being broken away, the hatch proper being closed, but the ventilating device open. Fig. 3 represents the same with the ventilator closed. Fig. 4: shows the hatch, with ventilator closed as shown Fig. 3, thrown open to show the interior construction.

Further referring to the drawings, in which like characters represent like parts throughout, A is the body of a car, and B the roof thereof.

0 represents one of the hatchways in the roof, and D the coaming surrounding the same.

E is a hatch or cover constructed in asubstantial manner, with theoutside timbers or framing c, the diagonal timbers e, and such other framework or bracing as may be desirable to furnish a solid and rigid structure. All that portion of the hatch not embraced between the timbers e e is covered with the decking e, the whole forminga solid and substantial construction, which is hinged to the hinge-cleat F by the hinges f. The V-shaped or triangular space between the timbers e e is covered or protected by a screen G of sufficiently-small mesh to keep out cinders and the like, and as a support for the same and as a protection against entry to the car through the same space a heavy screen of coarser mesh or metal bars 9 may be provided underneath the screen G. A hasp H, staple h, and sealing-hook h or other suitable means for fastening the hatch in the closed position are shown.

Within the aforesaid V shaped space formed by the timbers e e and the decking e laid thereon, and which trends lengthwise of the car or in the direction in which air-currents will be directed, are fitted two fanshaped lids I and I. The bodies of these lids may be of equal or unequal width but byreason of certain practical advantages in construction and application I prefer to make them unequal, as shown in the drawings. One of the lids--in this case the narrow one Icarries an extension-plate giving an overlap t of such dimensions that the width thereof added to that of its lid will approximately equal that of the lid I. The latter is provided with a staple-like projection or projections j, which pass through corresponding openings in the edge of the plate 2'. A hook and chain furnish means for fastening the lids together in the position shown in Fig. 2 or of securing the same in the closed position to the staple j, as shown in Fig.

f is a small opening in the hinge-cleat F, through which cinders and dust which might otherwise lodge on the screen G may be blown by the air-currents passing over the same. The rear ends of the lids are or may be truncate the breadth of this opening, as shown, so that when raised into the position shown in Fig. 2 they form, with the screen, a funnel, the spout of which registers with'this opening and through which cinders and dust may be forcibly expelled. When the lids are down, however, as in Fig. 3, these truncated ends shut against or slightly into the opening f and close it.

In the use of my ventilated hatch when ap- I plied to a refrigerator-car I take advantage of the ordinary ice holes or openings. These port the heavy hatch or cover.

are four in number-two at each end of the car-with their hatches opening away from and subject to various practical disadvantages, especially as they are required to sup- My improved ventilated hatch allows the screen or screens to be made stationary as an attachment to the hinged hatch, and when the ventilating device is used the auxiliary lids are simply raised and placed in posit-ion, where they have only their own weight to support and not that of a heavy cover in addition to their own.

It will be observed that in my device the operations of the hatch or cover proper and of the ventilating features thereof are separate and distinct from each other, though physically united. As ahatch or protection for the hatchway or opening the device may be used irrespective of whether the ventilating-lids are open or closed, and unless there is special reason for opening the same the hatch may remain closed while the ventilat ing-lids are adjusted; but when the hatch or cover is opened it lifts the ventilator and screen bodily with it from the hatchway and leaves thelatter clear and unobstructed.

When used in any position exposed to rain or drip, the overlapping lid is givensufficient slant to form a watershed. On a sloping roof this slant may be secured by placing the over-' lapping lid on the higher side. In a refrigerator or other car the hatches are preferably in pairs, so that the extension portion, plate, or wing shall be on the lid on the upper side of the car-roof and overlap the lower lid.

7 The embodiment of my invention'may be varied in many ways from the practical and operative device shown without departing from the spirit or principles thereof. I do not limit myself to the construction shown nor to the application to any particular kind of building, structure, car, or vehicle.

I claim as new and desire to secure by Letters Patent- 1. ,A hatch or cover for the hatchways of refrigerator-cars and the like, arranged on hinges ,to open bodily away from the hatchway and having aventilating-aperture therein, a protecting-screen for the said aperture mounted in said hatch, lids to close the aperture, and an extension plate or Wing on the one lid overlapping the other lid, the said lids being pivotally attached to said hatch and adapted when raised into mutually-inclined positions to form an air deflecting hood, substantially as described.

2. A hatch or cover for the hatchways of refrigerator-cars and the like, pivotally attached to the roof thereof and having a ventilating-aperture therein, a protecting-screen for 'saidaperture, fan-shaped lids to close the same, and an extension plate or wing on the one lid overlapping the other lid, the said lids being pivotally attached to the hatch on converging axes and adapted when raised to form an air-deflecting hood, substantially as shown and described.

3., A hatch or cover for the hatchways of refrigerator-cars and the like, pivotally attached to the roof thereof to open bodily away from the hatchway and having a ventilat-ing-apertu re therein, a protecting-screen for said aperture, fan-shaped lids to close the same, and an extension plate or wing on the one lid overlapping the other lid, the said lids being pivotally attached to the hatch on converging axes and adapted when raised to form an air-deflecting hood, substantially as shown and described.
